Lymphoma staging is not mentioned in Kaplan lecture notes
it's very important for the exam
here's a quick reminder

Stage 1: single lymph node or lymph node group
Stage 2: two or more LN or LNG on the same side of the diaphragm
Stage 3: both sides of the diaphragm
Stage 4: extranodal involvement such as bone marrow

I figured out that it is mentioned in Kaplan lecture notes but not in USMLE Step 1 but USMLE Step 2 CK notes.
